Henry's Law

What is Henry’s Law?

This law explains the relationship of gas solubility to pressure, it is named after English chemist William Henry (1774-1836).According to Henry’s Law, the gas solubility in a liquid is directly proportional to the partial pressure of the gas over the liquid. It can be written as follows:

frac{S_1}{P_1}=frac{S_2}{P_2}
